2- Claims.

This invention relates to protective devices in which a shield carriedby headgear is held normally in front of the users face, the shield.being swingable upwardly to bring it out of the users line of sight whenhe desires to have clear vision without face protection.

Some devices of the prior art include means to retain eye-protectivecolored lenses of a shield normally in the line of sight of averageusers. For example, my own Patent No. 1,601,830 shows shieldcarryinggear that comprises head and crown bands and a shield, having a window,pivotally mounted thereon. One of the pivot members is disposed throughtwo control members, one fixed on the headgear and the other on the sideof the shield body. Each of these members includes a disc that hasalternate radial ridges and furrows, and there is a stop to limitdownward movement of the shield. The two control members are urgedtogether by a spring, They so are related that downward movement of theshield is stopped when the window of the shield is in the line of sightof an average user. 1

Although the corelation of the control parts is such that the window isheld in the line of sight of users having heads of average relativeproportions, with other users the window is not always in the line ofsight when the shield is in front of the face. Moreover, it is desirablefor all users to be able to make adjustments to position the window toconform to their normal direction of work sight, and also to conform toabnormal conditions as when the work is low or overhead.

It is an object of the invention to provide emcient and easily alteredmeans to adjust the protective glass of a protective device both toconform to a users head proportions and to the line of sight he requiresfor his work.

When considered with the description herein, characteristics of theinvention are apparent in the accompanying drawings, forming parthereof, wherein an adaptation of the invention to a welders shield isdisclosed for purpose of explanation.

Like reference-characters refer to corresponding parts in the views ofthe drawing, of which- Fig. 1 is a side elevation of the shield;

Fig. 2 is a view of one of the control members;

Fig. 3 is a view of the other control member;

Fig. 4 is an enlarged view showing assembled control parts;

Fig. 5 is a rear elevation;

Fig. 6 is a section on line 6-6, Fig, 4;

Fig. 7 is a view of an alternative arrangement of control parts.

The headgear of the device comprises a head- 2 band H3 and a crownbandll fixed tothe headband at-diametrically opposite places. These twoparts may have means for adjustment of their size to conform to that ofa users head and other partsnot elsewhere referred to herein, as they donot relate directly to this invetnion.

The shield body comprisesa crown wall l2for top-of-the-head' protection,a front wall 13 for face-and-eye protection, a window M in the frontwall having transparent material (usually referred to in'the art aslenses); side members 16 for side-of-the-head protection, and a lowerwall it for chin protection, Reenforceme-nt fiat memhers is and is aresecured to the inner sides of the side walls i6.

The shield body is pivotally mounted on the headgear by a pin 29, at oneside, which is disposed through the member I8 and the head and crownbands ill-H, and by a diametrically opposite pin 2-! disposed throughthe head and crown bands, the member I9, and a side wall of the shieldbody. The pin 2| extendsoutside of the side walLar-rd there hasaremovable head 22 held thereon by a cotter-pin 23 or other suitablemeans, A spring 24 on the pin 2| is interposed between the head 22 andthe shield body side wall, and it is tensioned to urge the pinoutwardly.

A plate-like member 25, preferably of metal, is secured to the outsideof the headgear, as by being riveted at one end to the crownband. Thepin it is disposed through the other end portion of the member 25. Thatmember is formed with a rack 25, which as shown may have a plurality ofspaced holes or seats 2'! arranged transversely of the member.

A control element 28 is associated with member 25. It comprises a disc29, through which the pin 2| is disposed. The disc 29 is formed withradial V-shaped ribs 30. The disc 29 has an arm 32 of spring propertiesextending over the fixed member 25 and a pin or other projection 33capable of engaging the rack 26, whereby the disc 29 is prevented fromturning with respect to the headgear.

A control member 34, similar to and cooperable with the element 28,comprises a disc 35.

The disc 35 is formed with radial V-shaped ribs 38 of number, size, anddisposition corresponding to those of the disc 29. The pin 2| isdisposed through the disc 35, which is secured to a side wall of theshield body by having its arm 38 riveted or otherwise attached to thereenforcement member is.

A lip-like stop 39 on the'disc 35 protrudes into the path of movement ofthe arm 32, whereby swinging movement of the shield body is stopped whenit reaches its normal position.

The spring 24 urges the discs 29 and 35 together and normally keeps theribs 30 of disc 25 in the ribs 36-015 disc 25 and the shield body in theposition to which swung, and yet the spring yields to permit the ribs ofone disc to ride over those of .the other disc during swinging movementof the shield body. The ridges and furrows of the discs are of suchnumber and spacing that the shield body may be swung from and toposition in front of the users face by ridges shifting to the nextadjacent furrows.

The relationship of the radial ridges and furrows of the disc 29 to theheadgear and thus the position of the window of the shield body to theeyes of the user when arm 32 is against the stop 39 is determined by theposition of that arm with respect to the headband. When the medianhorizontal line of the window is not in the users line oi. sight or whenhe wants to raise or lower the direction of his view, he flexes the arm32 from the rack 26 to permit the arm 32 and thus the disc to be shiftedwith respect to the headgear. Thus the protective position of the shieldbody can be adjusted to meet the requirements of the user.

Instead of associating the fixed member 25 and the control member 28adjustable thereon directly with a part of the headgear and fixing thecontrol member 34 on the shield body wall, these parts may be reversed;that is, as shown in Fig. 7: As'seen in that view, the plate-like member25 is secured to the reenforcement member l9 and the control member 34is secured to the headgear,

with the cooperating parts in substantially the same relative positionsas hereinbefore explained.

Although the invention is described in association with a shield of thewelders type, it also is adaptable to protective devices of other types.For example, the adjustable control member 23 may be associated withheadgear in substantially the same manner as before described and the coacting control member 34 may be fixed to a member carrying an eyeshield.

I claim:

1. In a protectivedevice, a headgear member, a shield having a sidemember disposed outside of said headgear member, a pivot on one side ofthe device on which said members are mounted, a plate fixed to one ofsaid members adjacent to said pivot, a rack on said plate, a controlelement comprising a disc turnable on said pivot and a spring armdisposed over and cooperable with said rack, another control disc onsaid pivot fixed on said other member, said discs having interlockingradial ridges ridable over one another, a spring urging said discstogether, and a pivot on the other side of the device on which saidheadgear member and shield member are mounted.

2. In a protective device, a head contacting band, a shield having aside member disposed outside of said band, a pivot on one side of thedevice on which said band and side member are mounted, a rack fixed tosaid band, a control element swingable on said pivot and having a partcooperable with said rack, another control element on said pivot fixedon said shield side member, said control elements having cooperatingparts retraining relative turning movement thereof, a spring urging saidcontrol elements together, and a pivot on 'the other side of the deviceon which said band and shield side member are mounted.
